I assume that any integer can be written in the form for some value of

From this result it can be seen that whatever the value of the integer , will have a factor which is a multiple of 2 and a factor which is a multiple of 3. From this must be divisible by 6 as it is divisible by both 2 and 3. Thus, it is a multiple of 6

This is my first real attempt at proving anything so please do not be too harsh. Is it valid?

And for anyone well versed in LaTex, why has my second line of 's and 's changed like that?

Reason: Putting it in LaTex, and fixing it

Looks valid to me. And when you wanna do some more latex on a new line you should end the first line (/latex) and start a new (latex)(/latex) on the next line.

Or use these like this \\ sometimes it required \\ \\ to look neat but today it is just one set weird n and x on second line, what's going on? Does some funny stuff does tex, the different n is because I pressed enter after the \\.

Other things being equal, it's better to use separate [latex]...[/latex] blocks, because then each line is treated separately by the vBulletin system. It makes it easier for other people to put comments between lines etc.

I will bear that in mind in the future, cheers How come the n and x'es changed in the second line of my reply? Never seen that happen before.
